This invention relates to windshield operating mechanism and erateslidable windshields, like.

planetary plication of Carl B. Parsons,

cranks provides for a synchronous operation thereof.

The pivotal stud 23 of the lever 14 located to the right extends througha housing25 secured to the supporting member ,13 and enclosed withinthis housing is a counter-balanclng spring 26 anchored at one end as at27 'and connected at its other inner'end to the stud 23. The functionof, this spring is to counter-balance the weight of the windshield 22.

The other bell crank lever 14 is rotated by a handle 28 through theintermediary of a ing 29. While this gearing may be of any desiredconstruction it is preferably of the character describedand claimed iIithe ap- Serial #76,- 813, filed December 21, 1925. The handle 28 ismounted on the outer end of the stud 24 the other end of which extendsinto the. houslng 29 and carries the pinions of the plane` tary gearing.Thus the handle will be arranged in a position accessible to the driverFigure 2 is an enlarged fragmentary sectional view taken substantiallyon the plane indicated by line 2-2 in Figure 1 and Figure 3 is asectional view' taken substantially, on the plane indicated by line 3-3in Figure 1.

Referring now particularly to the drawing wherein like referencecharacters indicate like parts it will be noted that there isillustrated the header 10 of a motor vehi cle which is of a' hollowconstruction to accommodate the upper edge of thewindshield and of theoperating mechanism yet to be scribed and which includes as a partthereof a depending plate 11 peripherally secured to vthe header part-10 as for instance by means of screws 12.

Mounted within the header isy a plate-like bracket or supporting element13 which affordsa pivotal support for a 14 herein shown as crank leversincluding pair of levers triangular-shaped bell a pair of arms '15pivot-ally connected as at 16 by means of a link 17 and a pair of arms18 carrying stud?` .like rollers 19 adapted to engage in guides 20secured to the top frame 21 of the *wind-i shield 22.` These bell cranksare pivotally mounted as at their apexes member 13. which interconnectsthe pair of spaced tothe supporting It will be noted that the linlll1tling strips 35 i of the vehicle.

With the construction as' thus far described it will be apparent thatthe pair of levers 14 may be operated in unison to oscillate the sameabout their pivots whereby through their connection with the windshieldthey will irnpart ther'eto a vertical slidingv movement. -Obviously by.spacing the levers 14 longitudinally of the up er edge of the windshieldthe working e ort of these levers may be more eifctivl transmittedto thewindshield to cause t e same to slide up and down evenly and withoutbinding.

vIn Figure 3 the construction of the guides for the sides of thewindshield is illustrated. It will be noted that each pillar 30 isformed with a vertically extending shoulder 31 with which a. movablestrip 32 cooperates to form a. guide slot o-r groove to receive theadjacent edge of the windshield. VThe strip 32 is urged toward thewindshield by means of springs 33 interposed betweenv this strip and the:covering 34 of the pillar. Felt anti-ratwill preferabl be interposedbetween the edge of the win hield and the walls ofthe guide slot. Such aconstruction provides an eiiicient anti-rattlingconnection between thewindshield and side' pillars.

It Will further-y guiding meanssubstituted therefor. Reservation is therefore made to make such changes-in the details of -construction as found necessary or expedient and asmay come Within the purview of the accompanying claims. v

What I claim as my invention is:-

1. Thev combination of a slidable Windshield, of an operating mechanismtherefor including, .a pair of spaced leve-rs connected for parallelmovement, means connecting said levers to the Windshield, acounter-balancing spring associated With one lever and im operatinghandle connected to one of said evers.

ybalancing spring 3. In a Windshield operating mechanism,

a supporting element, a pair. of bell cranks pivotally mounting atspaced points on said supporting element, means for interconnecting saidbell cranks, means for connecting said bell cranks to the VWindshield tobe operated at spaced points means for Ioscillating one of said bellcranks.

4. In a Windshield operating mechanism, a supporting element, a pair ofbell cranks pivotally mounting at spaced points on said supportingelement, means for interconnecting said bell cranks, means forconnecting said bell cranks' to the Windshield to be operated at spacedpoints on the latter, a counterassociatedwith said bell cranks and meansfor operating -one of said bell cranks.

In testimony whereof Iaiiix my signature.
